Hundreds of people were injured in Cairo in renewed violence between security forces and protesters angered by the deaths of 74 fans at the football match between Port Said's Al Masry and Cairo's Al Ahly club.

The violence has quickly been channeled into a political contest, with many criticising the security forces for doing less to contain Wednesday's violence. "This was not a sports accident, this was a military massacre!" protesters in Cairo have been shouting, according to Sky News.

It follows a year of unrest in the North African state, which saw president Mubarak removed from power in one of the early changes of the Arab Spring.
